turns out when i ride the heel of my right shoe touches the
exhaust and the rubber of the heel was burning on the exhaust. lol,
EPIC.* easy fix, get some fine angel hair (stainless steel wool, no the drug
)
and use your bike for a few minutes, and when the exhaust it really hot
get that wool wet and scrub that nasty burned rubber off, after
that pass a dry, clean cotton rag/towel over the area to take
away residual rubber streaks, repeat if necessary, easy as pie!
(* use a towel or heavy glove or that steam WILL burn you,
but the steam is actually what gets that crap out with out
chemicals or scratching ur pipe).
I had the
same problem, all my boots are burnt, haha,
this makes a great conversation piece for weird ppl who
look at other people's shoes, anyway, so look, I crafted
an aluminum back-peg for my bike, prob solved, good luck.
